MOnrvmea designed primarilyeforl use as milk bottles,

one of its objects ing to provide a device of this character that can beroduced at low cost and can be sold at suc Ya ligure as to eilect asavin to the merchant who, when using the ordinary glass bottles, isrequired to meet certain regulations involving sealing, sterilizing,pasteurizing, etc., that are avoided Iby the use of the presentinvention.

Another object is to provide a paper bot tle having the appearance andproportions of a milk bottle whereby it can be used in lieu of a glassbottle at all stages of milk handlin it bei possible to use the standardmec nsms or filling the bottle, to inspect the contents of the bottlewithout openit, and so seal the bottle that the contents thereof cannotbe removed without detection. A

A further object is toconstruct 4a pa r bottle with interiorand-exterior shoul ers at the neck portion thereof for engagementbyastopperdiskandasealingca respec,

tively, whereby the opening of e bottle without mutilation is prevented.

A still further object is to provide a bottle made up of sections soassembled that the will constitute longitudinal and annularreinforcements.

With the foregoing and other objects in view which will appear as thedescription p the invention consists of certain novel details ofconstruction and combinatfilplilis if parvhich hereinlflte'lmore escrian in outn e aims, it understoodo that various changes may be mad; theconst'hiictoi:i and ai*- rangement o e parts wi out epartingomthespiritorsacnicinganyofthe advantages of the invention as-claimed.

. In the accom anying drae preferred form of einventionhas shown,

In said dra Figure 1 is an evation of the paper bottle constituting thepresentinvention.

2 is an enlarged longitudinal section erethrough.

3 is a section on line 3 3,- Figure Fiagure 4 is a section online 4 4,Fig- Figure 5^is a section through a portion of the bottle, the partsbeing shown separated. Referring to the figures by characters ofreference, 1 desi ates an oi'iter thickness of paper of suitab e gradesha into frusto conical form with its longitudinal edges` lapping, asshown at 2, to rovide a thickened ortion constitutingl a ongitudnalreinorcement. The lar end of this frusto conical portion is slig tlycontracted to .provide a short cylindrical portion 3. Fitted tightlywithin the outer thickness 1 is an inner thickness of pa er likewiseical with its lon tudmal edges `lapping, this inner thickness indicatedat 4 and its lapping ed at 5. .gfhe lap 5 is preferably diametriconstitutes a ongitudinal reinforcement. The two thickn have their smallends flush whilethe cylindrical portion 3 projects heyond the end of theinner thic 4. The portions 1 and 4 cooperate to form the upper taperedportion of the wall of the bottle and are rovided, near their small endswith o cooperat to form a' window or sight o 6.' A eet of snitabletransparent material, indicated at 7 extends across this window and hasits inarz ginal portions extended between the thick-V 1 and 4 and tightlgripped and held thereb A suitable a esive can be usedforhodingthesheet'in lace.

The lower portion of e bottle wall is made up of aninner thickness 8 andan outer thickness 9, both formed of a suitable gade of paper and bothcylindrical. Ea of theseth :News: haSllSl hldlnledge portions' lapping,as indica at 10 11 respectively, there'rv to provide longitudinalreinforcements. ese reinforcements are diametrically opsed andareadapted to aline with the pp' portions of the tapered part of the boe when the various The thickness' 8 is fitted tightly within thethickness 9 but projects therebeyond at one end as shown at 12, therebyto abut against the end of the thickness 4 lap the cylindrical portion3, which, in turn, abuts against the end of the outer thickne9.(SeeFigureS.) Abottomdisk con' 13, having an annular flange 14 dependingtherefrom, is ada ted to bear against the lower end of the ickness 8,and the outer thickness 9, which projects be ond the flange 14, isadapted to be turne in, as at 15 to bear against the bottom surface ofthe disk 13 and provide a channel 16 in which the ange 14 will rest. Itis to be understood that the paper forming thewall thick.

nesses and the bottom disk is suitably prepared to withstand the actionlof moisture and any suitable adhesive is employed to hold the partsassembled roperly.

Fitted on the small en portion of the bottle wall formed 'as described,is a paper ring 17 havin one edge inturned at 18 to provide a dou lethickness and present an exterior shoulder 19 and an interior shoulder20. Shoulder 20 is flush with the ends of the thicknesses 1 and 4 andcooperates therewith to provide a broad annular seat'or shoulder forsupporting the sealing disk of the bottle. Ring 17 is tapered and thusoverhangs said annular seat as shown.

The sealing disk has been illustrated at 21 and is formed of papersuitably treated. The diameter of disk 21 is substantially equal to thegreatest diameter of, the seat provided therefor and is greater than thediameter of the openin in the upper end of the ring 17. A circu ardepression 22 is formed in the disk and is so proportioned that when thedisk is fitted on its seat the depression will extend into the open endof the bottle wall and act as a plug. Spaced weakened portions arerovided in the disk,

as shown at 23 where y the disk can be` punctured readily when it is dsired to remove the contents of the bottle or when it is desired toremove the disk from its seat.

It will be apparent that the disk can not be placed in position on itsseat without snapping it into the contracted upper end of the ring 17 sothat it can restfirmly on the seat. Removal of the disk thereafterwithout detection is prevented because it ibecomes necessary toperforate it with some implement in order to properly engage andwithdraw it. By having s aced openings in the disk the contents of t ebottle can be poured out Without removing the disk.

For the purpose of sealing the disk in the bottle and protectin themouth of the bottle, there is provi ed a sealing cap also formed ofpaper and indicated generally at 24. This cap includes a disk having adepression 25 msertible into the neck ring 17 and ada ted to rest on andconstitute a backing or the disk 22. An annular flange is formed at themar 'n of the disk, as at 26 and is formed with an inturned edge portion27 providing an interior annular shoulder 28.- This inturned portion 27is slightly spaced from the surface of the flange sopas to be free toexpand slightly when forced over the large end of the neck rinrlg 17.

he sealing cap, which is of paper of suitable grade is renderedwaterproof in any suitable manner and has the necessary degree ofstiffness. The neck ring 17 is fixed to the wall of the bottle by asuitable adhesive and is also waterproof and of a suicient degree ofstiffness.

After the bottle has been filled the disk 22 is snapped into position asdescribed. The sealing cap is then forced over the neck rin 17 so thatthe depression 25 will bear against the disk, as shown in Figure 2 andthe shoulder 28 will snap under the shoulder 19 and fasten the cap tothe neck rin Thus the cap is held secnrel to place an cannot be removedfrom t e bottle without mutilating it.

A bottle such as described will with` stand the pressure exerted` by afilling machine and, when filled and sealed, will meet the re uirementsof the states and communities. ('he substitution of one grade of milkfor another grade without detection, is prevented, the window allows forproper inspection of the contents of the bottle, and as each bottle isto be discarded after use it is unnecessary to resort to sterilizng andpgsteurizin as heretofore. The use of a ttle of t is character makes itpossible for the producer to bottle the milk at the dairy and ship itdirect to the consumer, the construction of the bottle being such thatit will withstand rough usage without breakingvor leaking.
